Increasing Limb Temperature Improves Sensitivity of SFEMG for MG Diagnosis

As a lowly PGY1, I certainly don't have any hands-on experience with EMG, but I thought I'd share this new study in "European Neurology".

Sorry, I just have a link to the abstract since the full text isn't on Ovid yet...but it should soon enough.

Effect of High Temperature on Neuromuscular Jitter in Myasthenia Gravis

Obvious problem: small sample size (only 10 controls and 10 myasthenics)

Just wondering if any physiatrists out there are doing SFEMG.

It seems to be falling a little by the wayside and only used in cases where there is high clinical suspicion and maybe normal rep stim on NCV. Needles are pretty expensive and it takes a LOOONG time to do.

Very few do it. We had one give us a lecture on it in residency, but we never did any ourselves. I don't do it.
